+## [Unreleased]
+* 🖥️ [#947](https://github.com/fluttercommunity/chewie/pull/947): Add `ChewieController.disableFullScreenRoute` (default `false`). When `true`, toggling fullscreen no longer pushes/pops Chewie's internal fullscreen route — `isFullScreen` still flips so the control icon updates, but the player stays mounted in place and the host app owns the fullscreen presentation. Thanks [Ortes](https://github.com/Ortes).
+
 ## [1.15.0]
 * 🌐 [#946](https://github.com/fluttercommunity/chewie/pull/946): Web: enter the browser's native (OS-level) fullscreen via the Fullscreen API instead of only expanding the Flutter view inside the browser window. Pressing Escape to leave browser fullscreen also exits Chewie's fullscreen. Controlled by the new `ChewieController.useNativeFullScreenOnWeb` flag (defaults to `true`; no effect on non-web platforms). Thanks [Ortes](https://github.com/Ortes).
 * 🖱️ [#950](https://github.com/fluttercommunity/chewie/pull/950): Show click cursor on hover over Material controls and progress bar. Thanks [Ortes](https://github.com/Ortes).
